“…… I've read both of those articles you found for me, but I still can't distinguish between true periodontal bands and false periodontals, as well as the use of periodontal probes, and blood comes out as soon as you put it in, how can you judge this?"

After Chen Mo's reminder, Zhao Shiyi also remembered that the exam was about to take place.

Although there is only one day left, it is not fast to sharpen the gun, so you still have to work hard.

When Zhao Shiyi was eating, he pulled Yan Qingge to ask various questions. Chen Mo had Ruocun's great god to assist, but fortunately, she was not bad, and she pulled Yan Qingge, who was tied for first place.

Yan Qingge said: "The free gingival margin should be in the crown of the enamel cementum realm, and if the gingiva is inflammatory, edema, and proliferate, the gingival margin will move to the crown." At this time, combined with the position of the epithelium, if it does not change, there is no loss of attachment, and a pseudoperiodontal pocket will appear. However, if the bound epithelium moves towards the root, there is a loss of attachment, which forms a true periodontal pocket. ”

She held a notebook in her hand, drew a tooth with a pen, and the surrounding alveolar bone gums, and explained it to Zhao Shiyi in the form of a picture.

"You see, when periodontitis occurs, it combines with the epithelium and proliferates towards the root, and the crown part separates from the tooth surface to form a periodontal pocket, which is the healthy alveolar bone, and here is the damaged alveolar bone, you see, this area is the periodontal pocket. Yan Qingge likes to use a three-color pen to easily adjust the color at any time to make a clearer note.

"You also know that the probing depth of a healthy gingival sulcus is generally not more than 2~3 mm, and when the gingiva is severe, due to tissue edema and hyperplasia, the probing depth of the gingival sulcus can reach more than 3 millimeters, although the combined epithelium may proliferate to the root or side, in this position. ”

Zhao Shiyi stared at the pictures in the notebook, but in fact, she still didn't understand much.

Yan Qingge continued to explain: "The epithelial attachment position is still at the enamel bone boundary, and the enamel bone boundary cannot be detected clinically. How to distinguish gingivitis from periodontitis is to see if there is a loss of attachment. ”

Zhao Shiyi bit his finger and asked weakly: "Qingge, can you tell me again from the beginning, that is, from the place where the enamel bone realm starts......"

"Poof—"

Undisguised ridicule came from the side, Zhao Shiyi looked up, and saw Feng Tingting, who had not crossed paths for a long time, standing at the door of the dormitory building with her mobile phone, with a gloating face, she kindly said to Yan Qingge: "Some people will not understand even if you run out of saliva." It's just such a simple problem of periodontal pockets that I can't figure out, and I still want to be a dentist, so I change careers as soon as possible, and I can be regarded as a friend. ”

Zhao Shiyi lowered her head and didn't dare to raise her head again, Yan Qingge saw that the roots of her ears were as red as blood, and moved her eyes to Feng Tingting, who was watching the excitement.

"If you can't figure out a periodontal bag and have to change careers, then I don't know if you can't even distinguish between dental forceps by now, so you should go back to school and retake the college entrance examination. Yan Qingge's tone was as cold and steady as ever, she was not deliberately targeting Feng Tingting, but stating a fact.

Since Operation Smile, the interns have been reassigned to the department, and there is less intersection between them and Bai Lu Feng Tingting, even if they usually meet, no one will deliberately provoke trouble, and they have always been safe.

Feng Tingting was not afraid of the people in Chen Mo's dormitory, but she was afraid of Gu Zixun, who was getting closer and closer to them.

Originally, she still had some contact with Gu Zixun's friend Sun Zhe, but since Gu Zixun broke that lipstick, Sun Zhe has also become cold to her. Fortunately, she had followed Bai Lu to attend two gatherings held by Sun Zhe before, and some people were added, but these people all had a common characteristic, they were all more or less connected with Gu Zixun, and she learned from the words of these people that Gu Zixun's family background was very deep.

She also tried to talk about it, but when it came to the key points, everyone was secretive, such a mysterious person who made everyone avoid it, how could Feng Tingting not be afraid.

In addition to being afraid, she only felt that it was unfair, why, Bai Lu and Gu Zixun knew each other first, and she could have taken advantage of Bai Lu's east wind to rise to the top.

Since Yan Qingge appeared, he and Gu Zixun have gotten closer and closer, but Chen Mo and Zhao Shiyi have taken advantage of it together. Forget about others, Zhao Shiyi is stupid and stupid, and will only hide behind people and pretend to be pitiful, Chen Mo even directly attacked her, and she has not returned this hatred.

Yan Qingge is meticulous, and her professional ability is not to be said, she can't find faults, but her high-minded appearance is too contrived, as if she is the only one in the world who has the ability, in the end, it is not just by virtue of that face.

Feng Tingting to the four people in Yan Qingge's dormitory. It's not a day or two since she doesn't like it, and according to her observations, Gu Zixun has had a lot less communication with Yan Qingge during this time, and it is estimated that she has seen their true colors clearly, so she stayed away.

She saw Gu Zixun several times, saw Chen Mo and her group from a distance, and then turned around and walked away.

Today finally let her seize the opportunity, but she didn't expect that she accidentally took the wrong tooth extraction pliers two days ago, and she didn't say anything with the teacher at that time, but just asked her to pay attention to it in the future, and actually let Yan Qingge know.

"I just got the wrong one because I was too busy. Feng Tingting hurriedly defended herself and glanced at Zhao Shiyi disdainfully, "Even if I can't do it, I'm always better than her, she is equivalent to coming to our side to make up the numbers, and I don't like to be my stepping stone." ”

Zhao Shiyi pulled Yan Qingge's sleeve, glanced at Feng Tingting quickly, and said after taking a deep breath: "Qingge, the gentleman asks for himself, the villain asks for everyone, let's not waste time." ”

The voice was not lowered as she usually did, but the volume of normal conversation, not afraid of being heard at all, although there was still a little, very subtle trembling, but this was already a great improvement for Zhao Shiyi.

Feng Tingting glared at Zhao Shiyi like seeing a monster, and even Yan Qingge was surprised, Zhao Shiyi had always been the one who silently endured her anger, and the three of them had already habitually put her behind her and blocked her in front of her.

I don't know when, Zhao Shiyi no longer retreated, and began to try to use his brave side to face everything he had feared.

"Zhao Shiyi, you are sick, who you say is a villain, you are a villain. Although Feng Tingting didn't understand the meaning of what Zhao Shiyi said just now, she still understood the gentleman villain, she pointed at Zhao Shiyi, "I can pretend to be here if I know a few words that others don't know, as if you are very cultured, you don't even know what the difference between free gums is, you really know how to pretend." ”

Zhao Shiyi was told by Feng Tingting that she really couldn't even distinguish the basic organizational structure in her mouth, it can be said that when she was in college, she barely passed by relying on her roommates to cover up, and she also took the retake twice, and even some theoretical knowledge was only known after she came to the hospital.

This is a fact, and she has no way to refute it.

But it's just her, she doesn't want Yan Qingge to be ridiculed by Feng Tingting with her, she directly pulled Yan Qingge's hand, "Let's go back, call the cow and the horse, it doesn't matter." ”

Yan Qingge was dragged by Zhao Shiyi and walked two steps, Feng Tingting was still leaning on the door frame and making a sneering sound, Yan Qingge suddenly stopped, Zhao Shiyi looked back at her, and saw Yan Qingge's moon-like face with a smile, she took Zhao Shiyi's hand and gently pushed it down, and walked back to Feng Tingting.

If it were Zhao Shiyi, Feng Tingting would not be afraid at all, but in the face of Yan Qingge, she was full of mixed tastes in her heart, and the culprit was Yan Qingge who seduced Gu Zixun away, although she hated in her heart, she also knew that she was not as good as Yan Qingge in all aspects.

Facing a strong person who was better than herself in everything, she unconsciously straightened her back, preemptively struck inwardly, and said, "Do you want to quarrel, I'm not afraid of you." ”

"The gentleman seeks to himself, and the villain seeks to others, from the Analects of Wei Ling, which is the words of Confucius, which were later compiled into a book by his disciples. Therefore, just because you don't read much doesn't mean that no one knows. What does this sentence mean, if you are interested in going back and checking it yourself, you are not interested in being a Chinese teacher, after all, tutoring also has to be charged. ”

The shallow smile has always been on Yan Qingge's face, she is beautiful and beautiful, and now her smile is like a strange flower, and the jade is vibrant, Feng Tingting, who is usually used to Yan Qingge's cold expression, was slightly distracted by the peerless woman's smile in front of her.

Once some beauties are aggressive, the people who are shocked never have to distinguish between genders.

"It's not common to call cows and horses, and it's understandable that you don't understand the meaning, go back and flip through the book, prepare a book and write it down, otherwise it's just a few words of vernacular that are always turned over and over again, you don't get tired of talking, I'm tired of listening. ”

With such a strong sarcasm, Feng Tingting couldn't hear that she really became a fool, her face turned white and red, "You ......"

Yan Qingge smiled casually, "I thought about your language logic just now, and you said that you are more professional than Shi Yi, so she should be a stepping stone for you." Regardless of whether she will surpass you in the future, for now, compared to yours, you will not surpass me for at least ten years, but I don't want to use you as a stepping stone. ”

Needless to say, the words you don't deserve are already included in the unfinished words.

"Good night. Yan Qingge bowed politely, turned around and returned to Zhao Shiyi's side, Zhao Shiyi was dumbfounded, she never knew that Yan Qingge's mouth was so good.

The sentences hit the point, and there was no way to refute it, if Chen Mo heard it, I am afraid that he would not have to apprentice on the spot.

Feng Tingting was so angry that her lips were trembling, she stared at Yan Qingge who was in the back, her mind was on fire and she was about to catch up, as soon as she took a step, her hand was vigorously held, and Bai Lu pulled her hard and pulled her back to the dormitory.

"I'm going to fight that slut!"
